    Hi ,

     

    Could you please help me? 

    I've tried to create a 99999 records preffix list and it actually commited it.

    So now I have it. But it stopped commiting anything else.

     

    j# commit
    error: could not open configuration database (juniper.data+)

     

    So I can't even delete this large preffix list.

    Here is some diagnostic info:

    root@j% nand-mediack -C
    Media check on da0

     

    Although, found this what I think the reason is:

     

    root@j% fsck -y -f /dev/bo0s3f
    ** /dev/bo0s3f (NO WRITE)
    ** Last Mounted on /cf/var
    ** Phase 1 - Check Blocks and Sizes
    ** Phase 2 - Check Pathnames
    ** Phase 3 - Check Connectivity
    ** Phase 4 - Check Reference Counts
    UNREF FILE I=11168 OWNER=root MODE=100644
    SIZE=0 MTIME=Sep 3 17:35 2014
    CLEAR? no

    UNREF FILE I=11192 OWNER=root MODE=100644

    UNREF FILE I=11194 OWNER=root MODE=100640

    ** Phase 5 - Check Cyl groups
    494 files, 82677 used, 92641 free (761 frags, 11485 blocks, 0.4% fragmentation)

     

    Tried to unmount it - no luck:

     

    root@j% umount /dev/bo0s3f
    umount: unmount of /cf/var failed: Device busy
    root@j%

     

    Could you please tell me how to fix it?

    Is there a way of fixing it from cli? Or I have to restart router and somehow enter a single user mode? Or even use some kind of live-usb-flash drive? If so where could I get it?

     

    I use:

    leo@j> show version
    Hostname: j
    Model: srx210he
    JUNOS Software Release [12.1X46-D20.5]

    leo@j>

     

    Also does anyone know what configuration database limit is? If I could I would be willing to create a half a million records preffix list and use it for filtering traffic to stop any traffic from compromised (spam, botnets, advertising tracking) networks.

     

    If the limitation does not allow to use so many records is there a workaround? Like for example on cisco 867 there was not enough space to save large config, but you could enable archived/compressed mode and It could fit larger config.

     

    Thanks,

    Leo

    I decided to play the dirty way: Started root shell then: cd /config; mv juniper.conf.1.gz juniper.conf.gz; md5 juniper.conf.gz and renewed md5 sum in juniper.conf.md5 file. Then restarted and voila - it works as a charm. Now all what's left to do is to figure out what is the safe amount of network addresses for prefix lists without stuffing up the configuration database.
